    Are there foetal extracellular vesicles in maternal blood? Prospects for diagnostic biomarker discovery

    Prenatal diagnosis of congenital disease improves clinical outcomes; however, as many as 50% of congenital heart disease cases are missed by current ultrasound screening methods. This indicates a need for impr...

    Saccharide Microarrays for High-Throughput Interrogation of Glycan-Protein Binding Interactions

    This chapter describes two methods for fabricating microarrays of saccharides for display and interrogation with binding proteins, using fluorescence detection. The first approach is based on the rapid immobil...

    The Photorefractive Effect

    It is remarkable that photorefractive crystals, such as barium titanate, display such enormous optical nonlinearities with the minimum of optical intensity levels, typically no more than that output from a hel...
